10 an w/iom it may concern:

Be it known that I, ANDREWJ. SMITH, a

, citizen of the United States, residing at Los Angeles, in the county of Los Angeles and K State of California, have invented new and useful Improvements in Odometer Mountings and Locks for V ehicl s, 'of which the following is a specification. Ihe object of my invention is to provide an odometer mounting and lock such that the reading of the odometer may be always observed, but will revent the odometer being tampered with y any one but the owner of the vehicle. I accomplish this object by means of the device described herein and illustrated in the accompanying drawings, in which:- 1

Figure 1 is a sectional view showing a wheel hub equipped .with my improved odometer mounting andlock. Fig. 2 is an end elevation of the same. ,Fig. 3 is a sec tion taken on line 33 of- Fig. 1.

Heretofore odometcrs have been mounted on vehicles in such a. manner as to be easily tampered with by the driver using the vehicle so that the vehicle may have been driven many times as far as the odometer shows. The driver is thus enabled to collect .from his passengers the full fare for the dis tance actually traveled and afterwanls pays his employer for the-distance recorded by the odometer, keepingthe difference for him self. Drivers of private vehicles have also .beenienabled to use such vehicles for their own purposes by rendering the odometer inoporative for the time while they are using the vehicles.

My invention renders it impossible for any one but the vehicle. owner to have access to the odometer and thus enables him to know how far his vehicle has traveled.

Referring to the drawings, 5 designates a wheel hub equipped with spokes 6 clamped between flanges 7 and 8. To outer flange 8 is secured a drum 9 by means of cap screws 10 which are accessibleonly froin the inside of the drum. The outer end of drum 9 is interiorly threaded as at 11 and receives a cap ,12jwhich is provided with holes ,13 in its outer face to facilitate its being screwed into the end of drum-9. (lap 12 is provided on its inner face with ratchet teeth 14 which are adapted to engagewith bolt 15 of lock-16 .p l rigidly moubtedi'iril'lrum n. iiolt i5 is preterably a. spring bolt so that cap l2 may be turnedin one direction and will be held from rotation in the opposite direction until bolt 15 is retracted by the operation of lock us. By the. abovedescribed means it is rendered impossible t6 remove drum 9 from the. hub llange without unlocking, cap 12.

liigidly mounted on the end of axle nut 20 is an odometer 21 of usual construction. A flat spring 22 engages with the odometer casing and rotativcly locks the odometer casing to the hub to which spring 22 is rigidly allixcd. Shaft 23 of the odometer remains stationary as it is rigidlysecured to nut 20 which is stationary. A glass front 24- is provided in cap 12 through which the reading of the odometer may be seen.

It will be noted from the above. description that it is impossible to tamper with the odometer and falsity its reading without the use of a key to operate lock 16. It will be further noted that the odometer is always in a position where it may be read without the necessity of unlocking the case surrounding the fsame. od

and said revoluble member being rotatively secured to the hub of said wheel; a cylindrical casing for said odometer bolted to the hub of said wheel, the heads ofthe bolts proj ecting inside of said casing and a screw cap for said casing'adapted to be locked thereon.

In witness that I- claim the foregoing I have hereunto subscribed my name this 1st day of'June, 190 7.
